The heart consists of four main chambers: the right atrium and right ventricle, which receive deoxygenated blood from the body and pump it to the lungs, and the left atrium and left ventricle, which receive oxygenated blood from the lungs and distribute it throughout the body. Additionally, the heart has valves (the tricuspid, pulmonary, mitral, and aortic valves) that ensure unidirectional blood flow. It is also surrounded by the pericardium, which provides protection and support. The heart's rhythmic contractions are regulated by the electrical conduction system, including the sinoatrial node, known as the heart's natural pacemaker.
The haert pumps blood from the arteries and to the other parts of the body while the veins take blood into the heart.
